Add agentsfirst-mcp to Resources — public scorer for agent-readiness of any website

[joshuabaer]

What

capitalthought/agentsfirst is a public, free, MCP-native scorer that rates any website on its agent-readiness:

• robots.txt AI-agent rules (GPTBot / ClaudeBot / Google-Extended / etc.)
• /llms.txt and /AGENTS.md
• /.well-known/mcp-server-card.json and /agents.json
• Content negotiation for text/markdown
• Homepage references to MCP / CLI / SDK

Returns a 0–100 score, a Level 0–4 ('No agent access' → 'Agent-Driven'), per-dimension breakdown, and ranked top moves to improve the score.

Why I'm filing this here

Per the CONTRIBUTING guide, third-party server listings have been retired from the README in favor of the MCP Server Registry. I'll publish to the Registry separately.

But the Resources section of the README does seem like a natural fit for a public reference scorer (https://agentsfirst.dev/mcp) — it's a tool that helps developers building MCP servers and MCP-aware sites measure where they stand. Worth considering as a community resource alongside the existing entries?

Happy to open a PR for the Resources section if it'd be welcomed.

Try it

Point any MCP client at https://agentsfirst.dev/mcp — or one curl call:

curl -sS -X POST https://agentsfirst.dev/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"score_website","arguments":{"url":"https://YOUR-SITE.com"}}}'

Receipts

• Live scorer: https://agentsfirst.dev/mcp
• Framework spec: https://agentsfirst.dev/principles/
• npm: https://www.npmjs.com/package/@capitalthought/agentsfirst-mcp
• Sample data (27-site scoreboard): https://gist.github.com/joshuabaer/7f6f299f57612a7f2da4e93329cd4cf4

Open to whatever direction makes sense for the project — happy to defer entirely to the Registry path if that's preferred.
